摘要： A method of optimizing decoding of MPEG4 compliant coded signals is provided, comprising: disabling processing for non-main profile sections; performing reference frame padding; performing adaptive motion compensation. The method of decoding further including performing fast IDCT wherein an IDCT process is performed on profile signals but no IDCT is performed based on whether a 4×4 block may be all zero, or only DC transform coefficient is non-zero, and including CAVLC encoding of residual data. Reference frame padding comprises compensating for motion vectors extending beyond a reference frame by adding to at least the length and width of the reference frame. Adaptive motion compensation includes original block size compensation processing for chroma up to block sizes of 16×16.

摘要： An on-demand video delivery system, comprising: a program center having a content server for receiving and storing media signals representing humanly perceptible video programs and for converting the media signals into coded media data suitable for streaming over the Internet; and a plurality of delivery servers, each connected to the content server and the Internet for establishing an unicast link over the Internet with a respective one of a plurality of set top boxes (STBs) to deliver, upon request made from an STB for a video program, the requested video program by streaming over the Internet using Internet Protocol (IP), wherein each of the STBs includes: a buffer for receiving and temporarily storing a requested video program streamed from a delivery server over the Internet; a decoder for converting the coded media data to humanly perceptible video, and a processor for coordinating presentation of the humanly perceptible video to play on a television while the buffer receives packets of downstream coded media data from the respective delivery server.
摘要翻译：一种按需视频传送系统，包括：程序中心，具有内容服务器，用于接收和存储表示人为可感知视频节目的媒体信号，并用于将媒体信号转换成适合于通过互联网流式传输的编码媒体数据; 以及多个传送服务器，每个服务器连接到内容服务器和因特网，用于通过互联网与多个机顶盒（STB）中的相应的一个机顶盒（STB）建立单播链路，以便根据STB从视频提供请求程序，通过使用因特网协议（IP）通过互联网流式传输所请求的视频节目，其中每个STB包括：缓冲器，用于接收并临时存储通过因特网从传送服务器流传输的请求的视频节目; 用于将编码的媒体数据转换成人类可感知的视频的解码器，以及处理器，用于在缓冲器从相应的传送服务器接收到下游编码的媒体数据的分组的同时协调在电视上播放的人为可感知的视频的呈现。
